This is one of those videos where having too much time on one's hands actually paid off. So goddamn funky!

It's not real. This is just a play on the So-and-So Shreds series on Youtube. They take an actual performance and re-perform it so it sounds god awful. My favorite is Santana Shreds: http://www.youtube.com/watch?v=2BrLEuzVCVQ

The slate says '77, and the show was on until '82, so I believe this was just the last episode of the season, not the series.
